' This invention relates to a novel blanket com osecl wholly of animalfibres, which blan et is in many respects superior to and yetsubstantially less in cost than all-wool blankets of equivalent weight.v

Blankets made of all-Wool stand in a class apart from blankets composedpartly of cotton, both in their qualities and in the attitude of thepurchasing public toward them. The prejudice of the buying publichowever does not apply to silk and wool which have sometimes been cardedto ether and woven into an all-animal-f'ibre fabric, for example, as indress goods. Nor are such fabrics of silk and wool in fact inferior tofabrics composed wholly of wool, the essential characteristics of silkand wool, in that both are animal fibres, being similar as regardsabsorption of moisture, for example.

rll`he present invention is directed to a new orm of blanket which is anall-animal-fibre blanket and which will, therefore, sell, in competitionwith all-wool blankets and, moreover, has better characteristics thanallwool blankets of equivalent weight, and yet which may be produced atmuch less cost. the first time, the manufacture of a light or mediumweight, though strong and durable, all-animal-fibre blanketat a lowprice.

As an example of low cost al1-wool medium weight blankets that have beenon the market for years,-a 2 lb., 7 0X80 single blanket is typical. Inorder to weave satisfactorily, such a blanket is ordinarily made upL$545092 warp and l1O-55% filling. Thisenablesthe warp to be made lar eenough to weave properly when made o low grade wool Ystoc However, aconstruction of this typedoes not provide a very satisfactory texture orlofty nap, and therefore does not have the warmth which it would have ifit contained a larger percentage of filling. Also, there is so littlefilling in it that after na ping the blanket is tender in the llinommercial samples I havetested break rom zero to four lbs. per inch onthe Grab-test method. u

Heretofore it has not been thought possible to use less war because itwould unuLly weaken the blan et and would be -very Arior strengt of theblanket weight to made of the wool, 100

cult andreapensive to weave, but I have discovered that by providing,'instead of the ordinary heavy wool warp, a relativelysmall amount ofspun silk warp and an all-wool filling, preferably lll-25% waste fibrespun 55 silk war and 'Z5-90% wool filling, I can make a hlanketl whichis thicker, warmer, stronger,'and yet more flexible and durable, and ablanket having a loftier and denserr nap than an all-wool blanket ofequivalent ne weight, and this at an appreciably lower cost than that ofan all-Wool blanket of equal weight In the drawing:

Fig. t is an enlarged perspective'view of a im portion of the blanketmade in accordance with this invention but before the napping operationhas been performed; and

terrine to the drawing, the 'spun silk warp threads 2, of relativelysmall cross section as compared with wool, the silk constituting not to.exceed 25% blanket, are shown carrying thereon and interwoven therewithlarge, soft and loosetwisted wool lling threads 4 which constitute thebalance of the blanket. rIhe small size of the more lling threads oflarger diameter per inch, and' this relatively large size and amount offilling provides the thickness to give the warmth and a lofty close nap.By

the use of the silk warp I obtain the requisite strength both becausethe silk warp, relatively small in size and in quantity, 1s more p orless buried in the loose twisted filling, and remains substantiallyunteazled (and hence uninjured). despite the napping of the weft. w

The small size of the warp and its flexible character permit thestantally straight another instead of vthe warp threads. nap rll"hus thespun silk warp threads,

Actual tests have demonstrated that a blanket made in accordance withthis invention has the above f described advantages. Specificall as tostrength, my blanket is approximate y half again as strong war wise andtwo or three times as strong we wise than the typical al1-wool blanketsof equal f weight above referred to. The thickness and character of thenap are at once ap arent upon holding my blanket up to the lig t andfrom the feel of the blanket. Its insulating qualities are readily shownby physical heat transmission tests and demonstrate its superiority overthe all wool blankets as above mentioned. A

Havin described my invention, what I wish to claim and secure by LettersPatent is z 1. As a new article of manufacture, an allanimal-fibreblanket composed principally of napped, wool filling woven upon a spunsilk warp, the said warp not exceeding 25%-of the weight of saidblanket. 2. As a new article of manufacture, an al1- animal-fibreblanket com osed of v at least 75% of soft napped wool d) a spunvwastesil warp.

3. As a new article of manufacture, an allanimal-fibre blanket composedof substantially 7 5-90% by weight o soft napped wool filling woven u ona spun silk warp, the said vwarp constitutlng 10-25% of the weight oflthe blanket.

4. As a new article of manufacture, an allanimal-fiber blanket composedof wool for filling woven u on a spun silk' warp, said war not exceeding40% of the weight of said blan et and said filling being raised in asubstantial and lofty nap on both sides of the blanket.

5. As a new article of manufacture, an allanimal-fiber blanket composedprincipally of al relatively large soft wool nappedVV- filling wovenupon a relatively fine spun silk warp, said war not exceeding 40% oft-he weight of said b anket.

6. As a new article of manufacture an allanimal-fiber blanket composedprinci ally of a napped wool filling and a spun sill; warp, said warpnot exceeding 40% of the vweight of said blanket and being buried insaid filling.

As a new article of manufacture, an allanimal-ber blanket composed of anapped wool filling woven upon a silk warp, said warp composing not morethan 40% by e blanket.
